It's not that complicated. In order for you to have a 40% effective tax rate (including Federal, State, Local and FICA), assuming you ONLY took the standard deduction and you file single, you'd need an income of just over $450,000/year.

That assumes you have 1 exception, no deductions for retirement (which would actually reduce your effective rate) and only taking the standard deduction (you can't get lower!)
In fact, if you want to tax EVERY POSSIBLE tax into account (sales, property, fuel, etc), you'd need to make $300,000/year to achieve a 40% effective tax rate across all taxes.
So either you make a mountain of money, you have a terrible accountant, or you are lying.
Every time someone take about simplifying the tax code, I bring it up. It will hurt me as well (I'm poor) but it is ok.
If you're in the tax bracket to pay 40%, I'd say I want to raise your taxes you pay but I also want to raise the taxes your overlords pay.
I want higher taxes so we can offer the same services to the wealthy that we offer to the poor. It is the right thing to do. We don't have too many wealthy people in this country. We should be able to include everyone. Can't afford to include people who make too much money? Too bad. The program can't exist.
I would want to create a consensus towards "no income checks". The government should not have any program that qualifies people based on income or assets. Be it Medicare, social security, or Medicaid, food stamps, college tuition, rent subsidies, school lunch or whatever. You should not be able to exclude anyone because they make too much money or have too much money.
Of course, economists will say this is stupid and inefficient and irrational but I say economists are not even people. Nobody is rational in the real world.
